The evidence during the Yenikap subway and the Marmaray tunnel project revealed that the first settlements around the Golden Horn date back to at least the 7th century BC. Currently, the most visited destinations in Pier Lotti Hill, Eminonu, Galata, Karakoy, Miniaturk, and Eyup Sultan Mosque take place along the Golden Horn’s coasts. When Fatih Sultan Mehmet besieges the old city, Sultanahmet Constantine XI Palaiologos closes the Golden Horn for the Ottoman ship with a chain between Sarayburnu and Galata. Ottoman ships, however, passed through the chain walking by land from the Galata district. Today the coasts and the old city along it are the most attractive tourist destinations in Istanbul for four seasons.
